Abstract Scope |
This paper presents a methodology for the embedding of a sensor in a 316L stainless steel component during LPBF. The aim of this study is to overcome the drawbacks of traditional sensor attachment to the surface of components by embedding sensors into a part during the manufacturing process. A methodology for the embedding process that ensures the functionality of the sensor within the component is presented and an investigation into the effect of the embedding process on the part quality is reported. An off-the-shelf accelerometer was embedded into a turbine and tested under rotational loading conditions. The interface where the print was paused is also studied to investigate the effect of the embedding methodology on material properties. The embedded sensor is capable of detecting off-axis rotation and over-speed of the turbine; however, some tolerance issues are observed. Finally, based on the initial results, a more robust embedding methodology is proposed. |
